Application filed July 28, 1916. Serial No. 111,859.

To'aZZ whom it may concern Be it known that I, ALEKSANDER PLUnowsin, asubject of the Gzar'of Russia, residing at Waterbury, in the county ofNew Haven and State of Connecticut, have invented certain new and usefulImprovements in Lamp-Extinguishers, of which the following is aspecification.

This invention relates to certain new and useful improvemnts in lampextinguishers.

. The primary obj ectof the invention is the provision of a pneumaticdevice adapted for extinguishing the light in an ordinary lamp withoutthe necessity of bringing the hand of the operator near the chimney ofthe lamp.

A further object of the invention is the provision of a readyextinguisher for lamps formed as a part thereof when the lamp ismanufactured, the same being readily operable whenever desired for use.

A still further object is to provide a compressed air tank in connectionwith a lamp whereby an air blast controllable for extinguishing the lampis operatively arranged.

.Yth these general objects in view and others thatwill appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangementof parts hereinafter,more fully described, illustrated in the accompanying drawings,- andthen claimed.

In the drawings forming a part of- '35 application and in whichcharacters refer to corresponding parts throughout the several views:Figure 1 is a side elevation of a lamp provided with the present devicepartially shown in vertical section. Fig. 2 is a transverse sectionalview taken upon line 11-11 of Fig. 1. Fig. 3 is a front view ofthe airblast nozzle, and, Fig. A is a transverse sectional view thereof. Thepresent invention broadly consisting .in the provision of anextinguisher for lamps, the same is herein illustrated in connectionwith a kerosene lamp of. substantially the usual construction having anoil reservoir 11 with a burner 12 mounted there- '50 on, the latterbeing provided with a glass chimney .13 while a base it .is provided forsupporting the reservoir 11 by means of a pedestal 15.

. It will be understood that the reservoir this Specification of LettersIat'ent.

supporting pedestal and base may be integrally formed of glass or metalas found desirable, an axial bore 16 being herein provided in thepedestal communicating with the chamber 17 in the base 14. Acommunieating pipe 18 extends through the reservoir 11 from the bore 16to a point in the top of the reservoir 11 adjacent the burner 12, athreaded bushing 19 being provided in the upper end of the said pipe.-

A tubular casing 20 is fitted within the bore 16 having a closure cap21threaded upon its lower free end within the base chamber 17. Acentralpartition 22 is arrangedin'the casing 20 having a flap valve 23 upon itsinner face adapted for normally closing a valve opening 24 centrallyarranged in the said partition.

Anair compressing piston 25 is tightly fitted for reciprocating in thelower portion of the casing'20 having an operating rod 26 attachedthereto, the said rod extending axially of the said casing beingslidably arranged through a stuffing box 27 centrally carried bythe-casing cap 21. An air inlet port 28 is provided in the cap 21, itbeing understood that the piston 25 is valved in the usual manner sothatthe vertical reciprocations thereof by means of the rod 26 the inlet 28into the casing 20 and thence through the partition valve opening 24:into the upper portion of the casing 20. A handle 29 is arranged uponthe outerend of'the piston 26 while the latter has a hinge joint 30allowing the piston rod to be angularly bent and the free portionthereof to be engaged over a hook "31 in the'base chamberlT, asillustrated by dotted lines in Fig. 1 of the drawing.

Spaced plates are arranged adjacent the upper end of the casing 20having alining valve openings 33 therein while a slide port 35 extendingtherethrough normally maintained out of alinement with 33 by means ofa-spring 36. The valve 34 is provlded with a stem 37 projectingoutwardly of the pedestal 15 arrangedv with a finger piece 38 thereonwhereby the valve may be forced inwardly against the actionof the spring36 for bringing the port 35 thereof into alinement with openings 38,thereby allowing the compressed air within'the casing 20 to pass into.valve 3 1 closely fits between the said plates havlng a the smallchamber portion 39 in the upper end of the said casing so that the airmay freely pass through the pipe 18. A fanshaped nozzle 40 isscrew-threaded by means of a nipple 41 into the bushing 19, a pluralityof outlet perforations 42 being arranged in the face of the said nozzleadjacent the burner 12 in an inclined position beneath the horizontalair inlet plate 43 of the burner.

1n the operation of the device it will be understood that a piston 25will be actuated from time to time for the purpose of maintaining asupply of air under compression within the casing 20 between thepartition 22 and the plates When designed to extinguish the light of theburner 12, the flame of which is herein illustrated at 44, the fingerpiece 38 will be depressed thereby sliding the valve 34 to its openoperative position, allowing the compressed air to flow through the pipe18 and the nozzle 40. The air will thus be forced through theperforations 42 of the nozzle and will pass through the air receivingplate 43 of the burner, providing a draft for extinguishing the blaze 44by blowing out the same. A device is thus provided upon a lamp which isready for immediate use in extinguish ing the light and is readilyoperable by the hand when grasping the lamp supporting pedestal l5 andwithout the necessity of bringing any part of the body near the lampchimney 13, it being intended to prevent the accidental burning of theoperator during the extinguishing of the lamp.
